Solve by factoring (including splitting the middle term)
1. 3x2 – 15x + 12 = 0
2. x2 + 9 = 6x
3. (x + 4)2 + (x – 3)2 = 37
4. 2x2 – 7x – 10 = x2 + 2x
5. (4x2 + 3x + 20) + (x2 + 2x + 10) = 180
6. 2x2 + 3x = 5
Solve by the taking the square root of both sides.
7. 25x2 – 9 = 0
8. ¼(x + 5)2 + 9 = 19
9. 49x2 +36 = 0
10. 3(x – 2)2 – 6 = 42
Solve by the quadratic formula.
11. x2 – 8x + 4 = 0
12. (x – 2)2 + (2x)2 =13
13. 2x2 – 120 = -8x
14. -2x2 + 9x – 4 = 0
15. 3x2 + 1 – 8x = 0
16. 3x2 + 15x = 0
Solve by whatever method you choose.
17. (y +6) (2y - 7) = 0
19.
x  62  98
18. 4x2 – 5 = 0
20. 4x2 - 5x – 8 = 0
